Bad LSD being "a thing" and bad LSD being "a thing that causes bad trips" are very very different.
Among the things that people often sell as LSD, some have dangerously steep dose-response curves like 25I-NBOMe, some are pretty close analogues like AL-LAD.
None outright cause bad trips, and most or all of them are also sold with their proper labels and enjoyed by enthusiasts.
